It's possible that you ovulated cd17, the day of the 2nd + opk. Then this morning's temperature might be what is called a fallback shift - this happens when your temp drops on day 2 or 3 after ovulation. Keep temping & hopefully you'll see the temps jump back up to confirm o. Good luck!
Thank you really appreciate it :)
You may want to have it estimate you coverline based on temps only in you preferences if you don't have it set that way already. It looks like your coverline is way too high which makes things look more confusing. But I agree with PP! I had a fallback temp this month too, so there's still hope! Hopefully a couple more days will help clarify things for you. Best of luck! :)
Thanks! Do you know how to adjust your setting on the coverline? Not sure how to do so
